Gear motors are useful for providing a high rate of power at a range of different speeds, making them suitable for many different purposes, from minor applications such as intricate clockwork to massive industrial lifting. Whether you choose an AC or DC machine will depend on your particular application.
AC devices have a very simple construction, making them an economical choice in many situations. They are very commonly used across different industries, but still pose many disadvantages for the user or operator. While AC devices are very effective at high speeds, DC gear motors should be used whenever a low speed is required.
In many cases, the use of an AC or DC machine is largely interchangeable, although performance can usually be improved by selecting exactly the right motor for the machine. This includes choosing between an AC or DC device as well as choosing the right size of motor for your power and energy efficiency requirements.
Because the integrated gear box is designed to provide a high torque at a low speed, DC gear motors are often the highest performing option. These machines are able to provide a variety of different torque to speed ratios, meaning that precise movement and placement is easy in applications such as automotive, mechanical and industrial powering.
If you need reliability from your machine, even in tough conditions such as food processing or boating, then an AC device may be the right choice for you. Because of an overall simple construction, AC gear motors are generally more durable and suitable for constant operation over a long period of time.
